SHIPPING DEVICE FOR METAL PLANING AND SHAPING MACHINES.

SPECIFICATION forming part of Letters Patent No. 312,060, dated February 10, 1885.

Application filed March 1,1884. (No model.)

To @ZZ 1072/017@ it 11m/y concern:

Be it known that I, JOHN H. VRIGHT, a citizen ofthe United States, residing at Bridgeport, in the county of Faireld and State of Connecticut, have invented certain new and useful Improvements in Shipping Devices for Combined Metal Planers and Shapers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to that class of metalworking machines in which a reciprocating table is used; and it has for its object to produce a shipping device which shall be so constructed as to permit the table to be moved away from the tool in either direction with- `out interfering with the adjustment of the shipping-dogs, and which also will permit of quicker reciprocation of the table than has ever heretofore been accomplished-that is to say, I produce 'the reverse movement with a shorter throw of the table. I am thus enabled, rst, to examine the work at any time without being compelled to readjust the shipping mechanism,whereby much time is saved and, secondly, I accomplish a still more important result, in that I am able to combine the functions of a metal-Shaper with those of a metalplaner without change of parts.

Vith these ends in view my invention consists in the construction and combination of elements, as will be hereinafter fully described, and then pointed out in the claims.

In order that others may fully understand the construction and operation of my improved device, I will proceed to describe the same, referring by letters to the accompanying drawings, fo'rming part of this specification, in which- Figure l is a side elevation ofa portion of the bed and table of a metal-planer, showing one of the shipping-dogs, the outer shippinglever, and the tumbling-dog. Fig. 2-is a crosssection of the bed and the shipping-levers, with the shaft and tumbling-dog in elevation 3 and Fig. 3 is a side elevation of a portion of the bed and table, showing the shipping-dogs so adj usted that the table has but little throwas, for instance, when the machine is used as a Shaper.

A is the bed, and B the table.

C C represent the shipping-dogs, which are adj ustably secured in a groove, B', in the side of the table.

I have shown the shipping-dogs as secured .in the groove by means of a bolt and nut, the head of the bolt (not shown) engaging in the levers D and G, which I term shipping-le vers.77 rections in a straight line. projects upward, and at its end is pivoted a tumbling-dog, F. This tumbling-dog is pivoted to lever D at its outer lower corner, thus avoiding the use of a spring, as when thrown either into or out of operative position its own weight will hold it in that position.

It will be observed in the drawings that both of the operative faces of the tumblingdog are made concave, as at F. This is a very important feature of my invention, as in use the contact portions of the shipping-dogs pass into this concave portion, thus enabling me to so adjust the shipping-dogs that I am able to reciprocate the table in the space of half an inch, thereby giving to a metalplaner provided with my improved shipping device the additional functions of a metal-Shaper. In fact, I am able to cut a rectangular slot or groove to any depth and of any length from half an inch to the extreme capacity of the machine. The inner lever, G, projects downward in a direction diametrically opposite to lever D. A link, H, pivoted to this lever connects it with the clutch-operating mechanism, which may be of any kind, and forms no part of my present invention. I preferably These levers project in opposite diuse, however, in connection with this device the clutch-operating mechanism which forms the subject of my application for Letters Patent of even date herewith, Serial No. 122,569.

The operation of my present invention is as The outer one, D,

ICO

follows: Suppose,without regard to what may be the throw of the table, that it is desired to examine the work. To do so it is merely necessary to throwv the tumbling-dog into the position shown in Fig. 2, when the continued action of the feed will cause the table to pass away from the tool (not shown) in either direction that may be desired. Ihe shippingdogs do/not come in contact with lever D, but only with the tumbling-dog when it is in its operative position, as in Figs. l and 8.

The feed mechanism forms no part of my present invention, and none, therefore, has been illustrated. I preferably use. however, in connection with this device the feed mechanism which forms the subject of another apsubstituted for link H.

Having thus described my invention, I claimm 1. In a metal-Working machine, a shippinglever the operating portion of which is pivoted at its lower corners to the main portion thereof, and which may be throwninto or out of operati ve position, remaining iu'either posifion, whereby the reciprocation of the table 3 upon the table, as described, and for the pur- Y pose set forth.

3. |The tumbling-dog pivoted at its outer lower corner to the shipping-lever, whereby when thrown into or out of operative position the weight of the dog will hold it in such position.

4. Shipping-levers D and G and pivoted tumbling-dog F, having Vconcave sides F', in combination with shipping-dogs G, substantially as described.

5. Shaft E and the shipping-levers, in combination with a tumbling-dog having concave operating-faces and pivoted to one of the levers, and adjustable shipping-dogs, also having curved operating-faces, as described, and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN H. WRIGHT.
